COMBUSTION CHAMBER FOR STOVES.-

i' Application inea December 28, 192s. serial No. 329,036.

The present invention relates to combustion chambers for heating stoves, and the like, and aims to provide a combustion chamber with an air entry channel for delivering heated jets or streams of air into the combustion chamber, thereby supplying air to the unburned gases and igniting them before they can escape into the flue, as well as having a tendency to reflect the heat toward the Hoor.

A further Object is the provision of a combustion chamber composed of sections Ofnovel form and assembly to provide the air entry channel.

Another Obj ect is the provision of an air entry channel of arched form extending upwardly along opposite sides of the combustion chamber and across the top thereof, and provided with apertures for directing the air downwardly into the combustion chamber. v

With the foregoing and other objects in View, which will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein- Figure 1 is a view of the improved combustion chamber, partly in front View, and partly in section on the line 1-1 of Fig. 2.

Fig. 2 is a View partly in bottom plan view, and partly in section on the line 2-2 of Fig. 1.

Fig. 3 is a sectional detail on the line 3-3 of Fig. 1.

The combustion chamber isr composed of the front and back sections 7 and 8 `which are separate castings. The front section has the door opening 9, while the back section has the Outlet 10 for the products of r combustion.

The combustion chamber is divided along its sides and top, and the adjacent edge portions of the sections 7 and 8 are formed with the complementary offsets 11 and 12, 're- The offsets 11 and 12 provide a channel which is arched so as to bridge the combustion chamber, and bolts 15 extend through the offsets 11 and 12 for clamping them together and securing the sections 7 and 8 together. The ends of the channel are preferably enlarged, as at 16, and open downwardly for the upward flow of air into the opposite ends of the channel.

Plates 17 are disposed across the side portions of the channel, and a plate 18 is disposed across the upper portion of the channel, the edges of said plates being seated in rabbets along the channel, as seen in Figs. 2 and 3. Bolts 19 extend through the plates 17, 18 and Offset 11 to clamp said plates in place, and the end portions 20 of the plate 18 overlap the upper end portions of the plates 17.

The top plate 18 has apertures 21 for directing jets or streamsy of air downwardly into the combustion chamber so that the air reaches the unburned gases and ignites them before they can escape through the outlet into the flue. The air fiowing into the channel is heated so as to more effectively ignite -the unburned gas and particles before they reach the outlet 10. The reflection of the hot blast toward the fire has produced a feature of commercial value in that it has demonstrated that the heat is reflected toward the floor.

Having thus described the invention, what is claimed as new is i- 1. A combustion chamber comprising sections having offsets fitted together to provide an air entry channel, and plates extending across said channel and the joint be-` tween said oflsets and having apertures for the How of air into the combustion chamber.

2. A combustion chamber comprising sections having offsets fitted together' to provide an arched channel, and plates secured` across said channel and including a plate at the top of thecombustion chamber having apertures opening downwardly for the flow `of air into the combustion chamber.

3. A combustion chamber comprising front and back sections having offsets fitted together to provide an arched channel, and l 4. A combustion chamber comprising seoside thereof, said plates and portions of said tions having a joint, and plates extending sections along said joint providing an arched 10 across said joint, said plates and portions air passage open at its ends and having .of said sections along said joint providing downwardly opening apertures at its inter- 5 an air passage. mediate portion.

5. A combustion chamber comprising seo- In testimony whereof I hereunto aflix my tions having a joint7 and plates secured to signature. said sections across said joint at the inner HENRY LANGE.
